Reduced-port surgery for right paraduodenal hernia in an adult patient: A case report and review of the literature

Paraduodenal hernia (PDH) is a congenital internal hernia caused by an abnormal rotation of the midgut during embryotic life; it is characterized as right- or left-sided according to the hernial sac location. Herein, we describe a case of a 30-year-old male patient who was preoperatively diagnosed with right PDH and underwent successful laparoscopic repair using reduced-port surgery (RPS). The patient presented with postprandial nausea, vomiting, and upper abdominal pain. Contrast-enhanced CT and an upper gastric series led to the preoperative diagnosis of right PDH associated with intestinal malrotation. Thereafter, laparoscopic repair using RPS was performed. After the small bowels were reduced from the hernial sac, the hernial orifice was opened widely and laterally. The postoperative course was uneventful. This is the first report of a successful laparoscopic surgery on right PDH using RPS.
